ANALISIS KUALITAS AIR PADA KOLAM INTENSIF DAN SEMI INTENSIF IKAN MAS (Cyprinus carpio) DI INSTALASI BUDIDAYA AIR TAWAR (IBAT) PUNTEN BATU JAWA TIMUR

Carp (Cyprinus carpio L) is one type of freshwater fish whose demand is very much on the market. Goldfish have many varieties with different characteristics including, consumption fish and ornamental fish. Ornamental fish are kancra domas goldfish, glass, kumpay, and koi. Punten carp is one of the first varieties of carp in Punten. The purpose of this study was to determine which parameters were optimal and efficient from water quality parameters using intensive and semi-intensive ponds because water quality parameters were an important role in carp cultivation. The results of statistical analysis prove that the average and standard deviation (SD) for all parameters, namely physical parameters include (temperature, brightness, depth, and color) and chemical parameters including (pH, DO, NH3, Nitrate (NO3), Nitrite (NO2) as a whole is suitable for use in the process of measuring water quality in intensive ponds and semi-intensive ponds for the first week and second week.Based on the measurement results obtained the largest value for the mean (mean) in the intensive pool is 81.67, whereas in semi-intensive ponds of 125.56. Then the largest value for standard deviation (SD) of 20.17 in brightness parameters in intensive ponds and the largest value for standard deviation (SD) of 24.31 in depth parameters in semi-intensive ponds .
